One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream. In this article, we shall take a look at the differences between the nervous system and the endocrine system in detail.
Nervous System vs Endocrine system
| Nervous System | Endocrine System |
| Electrical impulses are the messengers in the nervous system | Hormones are the chemical messengers in the endocrine system that target cells through the bloodstream |
| Brain and the spinal cord constitute the nervous system | Glands and organs like thyroid, pituitary glands and reproductive organs (ovaries and testes) are involved in the endocrine system |
| Nerve impulses are transmitted through neurons | Hormones are transmitted through blood vessels |
| The nervous system is under both voluntary and involuntary control | The endocrine system is under involuntary control |
| Nerve impulses make use of the neurotransmitters at synaptic clefts and sodium and potassium channels and enter the target cells. | The hormones enter into the target cells by diffusing through the plasma membrane or by binding to the cell receptors |
| Responses are localised | Responses are widespread |
Both the nervous system and endocrine system give signals to the internal body parts. To learn more differences, visit BYJU’S Biology.
